From your description, I would strongly recommend replacing the power
supply. Unfortunately, HPaq uses cheap Bestec power supplies in its
Presario and Pavilion products. Bestec is the same junk brand that made
eMachine computers famous for system failures. When a Bestec power
supply fails, more than likely it will take the motherboard along with
it. Furthermore, this power supply is rated at an anemic 200w,
according to the HP web site.

I am fairly certain that the dimensions of the power supply are standard
in the modern Presarios, so you need a good quality replacement that has
a 20-pin ATX power connector plus the auxiliary 4-pin 12v connector used
by many motherboards. 250w or 300w would be far better than 200w.

You might also clean the inside of the chassis with a can of compressed
air, some q-tips and maybe a soft-bristle artist's brush. Dust and dirt
can keep the air from flowing properly inside and cause overheating.
Pay attention to the rotating fans inside the power supply and on the
processor heat sink... Ben Myers
